Exchange Rate Systems and History

Historical and structural pages on adjustable pegs, target zones, dirty floating, Bretton Woods, Smithsonian parities, the dollar standard, and the macroeconomic trilemma.

Exchange-rate systems only make sense when read in context. Fixed pegs, target zones, dirty floats, and floating systems all respond to the same pressure: how much policy freedom a country is willing to trade for exchange-rate stability.

This branch keeps the historical and structural pages together so readers can move from the broad regime concept to the specific systems that shaped modern currency management.

Key pages in this branch include adjustable pegs, target zones, dirty floating, the Bretton Woods framework, the Smithsonian realignment, the dollar standard, and the macroeconomic trilemma.
